LEVI F. KNODERER, OF COLUMBUS, OHIO.

STAND-BOILER.

SPECIFICATION forming part of Letters Patent No. 768,859 dated August 30, 1904.

Application filed March 3, 1904. Serial No- 19s,3s4.. (N0 model.)

To all whom it may concern:

Be it known that I. LEVI F. KNODERER, a citizen of the United States, residing at C0- lumbus, in the county of Franklin and State of Ohio, have invented a certain new and useful Improvement in Stand-Boilers, of which the following is a specification.

My invention relates to an improvementin stand-boilers.

The object of the invention is to provide an eflicient and simple heating means in combination with a casing entirely surrounding the boiler whereby the products of combustion are caused to circulate around the latter, thus being thoroughly exhausted of their heating properties before escaping.

Another feature resides in the burner,which is so formed as to be readily assembled and placed in position beneath the boiler. A further novel point lies in an integral ring plate, which will be hereinafter referred to.

Finally, the object of the invention is to provide a device of the character described that will be strong, durable, efficient and one that will be comparatively simple and inexpensive to construct and also one in which the parts will not be liable to get out of working order.

IVith the above and other objects in view the invention consists of the novel details of construction and operation, a preferable embodiment of which is described in the specification, and illustrated in the accompanying drawings, wherein Figure 1 is a vertical sectional View. Fig. 2 is a top plan view of the ring. Fig. 3 is a detail partial sectional view of the burner.

Similar numerals refer to similar parts throughout the several views.

In the drawings the numeral 1 designates the boiler, which is of the ordinary construction and is provided with the usual inlet-pipe 2 and outlet-pipe 3 and the clean-out pipe 4, having the cock 5. The boiler 1 is inclosed by a cylindrical casing 6, formed with an outlet 7 near its upper end. which is suitably connected with a proper flue. The casing 6 is larger in diameter than the boiler, thus forming a chamber around which the products of combustion circulate. The lower end of the casing rests on a ring plate 8 and is held in place by the guard-flange 9. Upwardlyextending lugs 10 from the plate 8 are formed with seats 11, in which sets the lower peripheral end of the boiler. I preferably employ three of the lugs, as shown in Fig. 2, although I may use more. The ring plate 8 is supported by an ordinary stand 12, provided with the usual curved arms 13, which are held in fixed relation to the plate 8 by the downwardly-projecting annular flange 1 1. It is evident that the flange allows a ready assembling of the plate and the stand, whereby the same are fixedly secured together in a simple and eificient manner. It is to be observed that the guard flanges 9, lugs 10, annular flange 14,'and lip 18 are formed integral with the ring plate 8, thus providing a plate which may be cast, thereby greatly simplifying the construction of the device.

For heating the boiler I employ a gas-burner comprising a cylindrical mixing-chamber 15, having an open lower end and a flaring upper end 16, formed with a laterally-projecting annular flange 17, by which the burner is supported in an annular lip 18, formed in the ring plate and having its upper surfaceflush with the ring plate. Gas is supplied to the chamber by a pipe 19, Where it is mixed with air entering through the lower end of the chamber to form a combustible product. Supported centrally and flush with the upper end of the mixing-chamber is a deflectorplate 20, resting on legs 21, formed integral with the chamber, and provided with contracted ends 22, which pass through apertures'in the plate and which may be upset to secure the plate in place. The plate is smaller in diameter than the opening at the end 16, which, owing to its flaring Walls, radiates the products which pass upward around the edge of the deflector-plate 20.

The products having been ignited and passing up against the plate 20 are deflected thereby against the flaring walls of the end 16, by which they are radiated, passing around the edge of the said plate. The radiating or spreading of the products causes them to circulate upward around the boiler within the casing, thereby thoroughly heating the boiler and escaping through the outlet 7 practically spent.

It is Wholly Within the province of my invention to arrange Within the mixing-chamber 15 a suitable gasolene-burner, as it may be desirable to use gasolene as a fuel instead of gas.

It is apparent that the device is quite simple and that a greatly-increased heating of the boiler is attained through the casing and the burner.

I do not Wish to limit myself to the exact details of operation and construction herein set forth, as 1 may make various changes in the same Without departing from the spirit of my invention.

Having now fully described my invention, what 1 claim as new, and desire to secure by Letters Patent, is

1. In a device of the type set forth, a boiler, a casing inclosing the same, a stand therefor and a burner, in combination With a ring plate having a central opening and comprising, a guard-flange engaging the casing, lugs formed with seats to receive the boiler, an annular flange engaging the stand, and a lip formed about the opening and adapted to support the burner.

3. In a device of the type set forth, a boiler,

a casing having an outlet and surrounding the boiler, a plate having a central opening and supporting the boiler and the casing, a stand for supporting the plate, in combination with a burner comprising a cylindrical mixingchamber having aflaring en'd supported by the plate Within the opening thereof, a deflector-plate Within the flaring end of the chamber, legs from the chamber for supporting the plate, and. means for supplying fuel to the burner.
